Dr. Hook,
Thank you very much for the information. I am much less confused and reassured that protected sex is, while not zero risk, very low risk for hsv.
As I have said and others before, both your and Dr. HHH's services are invaluable. Thanks again.
Welcome back to our Forum. You have clearly researched the topic you ask about and thus I think my job has more to do with providing you with a context for evaluating your risk than anything else.
Background facts:
About 20% of American adults have HSV-2 and of these, most do not know it. Thus there is a small chance that any sexual encounter with a person who has ever had sex before could be with an infected partner. BUT, the chance of transmission at any single act of intercourse with an infected partner is less than 1 in 1,000 and, if the partner is asymptomatic, is probably less than 1 in 10,000 - this is a very small chance. Further, condoms clear reduce the risk of getting herpes by 50-60% (this is a conservative estimate). Putting all of these numbers together, the mathematical risk of getting HSV from sex with a new partner who does not know they have HSV is less than 1 in 100,000 and probably lower.
There is a theoretical chance of getting HSV from sexual contact with an area not protected by a condom but that too is small as over 80% of HSV lesions occur in areas that are typically covered by condoms.
Thus, using these numbers, the risk of getting HSV from condom protected sex is very, very small and probably not something to worry about. I realize you would like a precise answer but as indicated above, there are many, many variable influencing the risk. My suggestion is to take the sorts of precautions you have mentioned and not worry. EWH
